Title: Improvements in sliding gate valves
Inventor: BATES KENNETH WILLIAM
IPC: B22D41/26
Filed: 1981-11-26
Abstract: A semi-rotary sliding gate valve has spaced-apart mounting and support plates (15, 30) and three orificed refractory valve bodies (20, 21, 22) pressed into leak-tight facial contact by spring means (33) carried by the support plate (30). The two plates (15, 30) are held together by three identical clamping attachments (31), two of which serve as a hinge connection; release of the third attachment (31) enables the support plate (30) to be swung away from the mounting plate for inspection and renewal of the valve bodies (20, 21, 22). Each attachment features a clevis (61) and eyebolt (62), wherein the clevis (61) of predetermined dimensions serves to establish a preset set distance between the plates upon reassembly of the valve and thus to re-establish a previously set level of spring-biassing upon the valve bodies (20, 21, 22). <IMAGE>

Title: An actuator for an internal shoe drum brake
IPC: F16D65/22
Filed: 1982-04-07
Abstract: A cylinder housing (20) between opposed shoe-ends (14'', 16'') is floatingly guided in the direction of its cylinder axis (B) on a plate-shaped brake carrier (10) and acts against shoe-end (16''), whilst piston (36) guided in housing (20) acts on the shoe-end (14'') upon hydraulic actuation of the brake. Extending through carrier (10) is a lever (66) having its part located in the interior of the brake mounted to housing (20) and having its outer part connected to an actuating cable (70) of a Bowden wire (70, 72). The lever (66) has a strut (78) articulated to it, which bears against second shoe-end (14''). The axis (C) about which lever (66) is pivotable on housing (20) is further away from the plane (E) in which the cylinder housing (20) is guided than the axis (D) of the articulation of the lever (66) to the strut (78). The conduit (72) of the Bowden wire (70, 72) bears against housing (20) in such a way that upon mechanical actuation of the brake the moments exerted on the cylinder housing (20) by the conduit (72), by the lever (66) and by the first shoe-end (16'') are approximately in equilibrium to stop tipping. Wear adjustment is by a pawl (86) and nut (30). A spring (94) yields at a certain force to allow pawl (86) to stand still to prevent overadjustment. To preclude adjustment on overheating a bimetal spring [102] mounted on housing (20) acts on pawl (86) to disengage it (see e.g. Figure 5). <IMAGE>

Title: Pressure-controlled valve
Inventor: BENNETT FREDERICK WILLIAM
IPC: A62C13/76
Filed: 1983-02-16
Abstract: An automatic valve (1) is fitted to a pressurised fire extinguisher shell (2) and has a valve member (5) incorporated in a piston (7). The extinguisher pressure is transmitted through a restricted bleed passage (12, 13) to a chamber (14) over the top of the piston to keep the valve member seated against the same pressure acting over a smaller area in the extinguishant outlet passage (3). A nylon tube (20) or equivalent type of fire detector is connected through a port (P3) to the chamber (14) and pressurised therewith. Rupture of the detector (20) vents the chamber (14) with the result that the pressure force acting on the top of the valve member piston (5/7) falls below that acting on its lower face and the valve shifts upwardly to supply the extinguishant from the passage (3) to a discharge tube (17); at the same time the opening of the bleed passage (12) to the chamber (14) through an annular port (11B) is cut off by the piston (7) to prevent loss of propellant through the open detector (20). <IMAGE>

Title: Leakage volume flow-free braking valve
Inventor: KAMM GOTZ
IPC: F15B13/01
Filed: 1984-07-11
Abstract: A leakage volume flow-free braking valve, for control in respect of speed, independently of load, of double actuating pressure fluid load devices 14 which are subjected to a tensile loading, includes a shut-off piston 2 provided with axial throttle grooves 6 forming an adjustable main throttle 6 which is closed in the initial position, the end face (16) of the control piston (4) which is remote from the shut-off piston (2) and which defines the control pressure chamber (18) is larger in known manner than the end face (27) of the shut-off piston (12) is remote from the load pressure chamber (13) and which defines the drain chamber (28) which communicates with the drain port (8) of the valve. In the event of a change in load in the braking mode, as in the case of a universal digger with deep bucket during a ditch digging operation, the annular piston area of the device (14) must be subjected to operating pressure, the load pressure drops and thus also the pressure in compensation pressure chamber (25) immediately falls to drain pressure. Unlike the normal braking mode the feed pressure can now act on the entire end face (14) of the control piston (4), acting as a control face. <IMAGE>
